My invention relates to television appara pressions to be transmitted to a Suitable re- A ceiving device and there projected upon a screen.-

principal purpose of this invention to provide means whereby a subject which is being transmitted by the apparatus may be more readilyreached as it moves around and a larger range for a given'appa ratus attained. 7

' One of the difficulties encountered 1n the use o fi'apparatus of this character lies in the 1 fact that where a group of subjects, such,

for instance, as actors upon a stage, are to obe'trans'mitted, the machine sounwieldy that it cannot be readily movedso asto take in the entire width of the'group, and-'at'the present time it is impracticable to take a very large section of view without'shifting the machine; This invention contemplates the provision of means whereby the machine may be readily trained upon adifferent subject at a distance from the first subject with a minimum amount of effort and delay.

I'will describe one form which the invention may take by reference to the accompanying' drawings, wherein-=- .Fig; 1 illustrates a television transmitting apparatus having, my invention applied thereto; and v j p Fig.'2 is a top plan view of-the same de-- v1ce." 1. j Referring now in detail to the drawings, I showat 5 a casing wherein the means for causinglight' reflections from a subject in order that they may be converted into electrical energy that may betransmitted over wires or via radio, is housed. The-aparatus for converting the light reflections rom the subject into electrical energy-is not containedin casing 5, but on separate tripods, and is not involved in'this application.

asing 5 contains a motor for a scanning disc, and control apparatus for the motor and light source. This casing 5 is mounted upon a pedestal 6 suitably supported bi casters, such as 7 and 8, so that it may e moved around the room. At 9 I indicate the light.

Normally, this lens itself wouldbe trained upon the subject that 55. wieldy machine'is to be shifted around each time the subject changes position, or each time a new subject is to be transmitted, a very slow and unsatisfactory change must result. I therefore provide means whereby ft'he'subject may be followed without the necessity of shifting the machine, so, long as the subject remains within certain limits.

This means consists of amirror 13- mounted' in front of the lens 12 and so mounted that it .65 any one of several angles relative to the machine. That is to say,the angle at which the light strikes the" mirror 13 from the lens will, of course, be the angle at which it will the mirror in a ball and socket joint, as

other without in any way disturbing the transmitting machine and subjecting it to jars that might cause distortion in the image transmitted. It is especially useful where a group of subjects, such as actors on a stage, are being transmitted; although, of course it is applicable to any situation where it is desired to change from one subject to another rapidly or to follow a moving subject.

aving thus described my invention','what I 'claim as new and desire to secure by Letters Patent is: o

v 1.- In television apparatus, a; device hav in'gv means for directing a beam of light through a scanning disk and. a lens, means 100 7o leave the mirror, and by changing the angle associated with said lens for directing the light emanating therefrom in any one of several directions comprising an arm on said device having an extension projecting to a point adjacent the outer end of said lens, and a mirror adjustably mounted on said exten sion in the field of View of said lens.

2. In television apparatus, a device having means for'directing a beam of light through a scanning disk and a lens, means associated with said lens for directing the light emanating therefrom in vany one of several directions comprising an arm on said device having an extension projecting to a point adjacent the outer end of said lens, and

a mirror adjustably mounted on said extension in the field of view of said mirror and arm being connected by a ball and socket joint.

In witness whereof, I hereunto subscribe my name this 8th day of February A. 1D,,
